Cheap Flights to National City from HK$691

If you're not prepared, air travel can be testing. But there's no need to panic. Follow these tips and tricks for a trouble-free start to your time in National City.What to pack in your hand luggage:

• Traveling on a plane can be a great experience if you take the right gear. Firstly, you'll want some basic toiletries, such as toothpaste, a toothbrush and some deodorant, a fresh set of clothes and a good read. Next, find room in your hand luggage for your laptop, a charger, any daily medications and maybe a comfy neck pillow too. Last, but definitely not least, don't forget to bring your passport, travel documents and your credit cards.

Do not pack the following items in your hand luggage:

• Leave all your full-sized bottles of shampoo and conditioner in your checked luggage. Any liquids or gels in your carry-on suitcase larger than 3.4 ounces (100 milliliters) will be confiscated by security. Pointed or sharp objects, like your treasured Swiss Army knife, and dangerous products which are flammable or explosive, such as flares, chemicals agents and strong acids, are also prohibited.

What to wear on a flight:

• Comfort should be your number one priority when picking what to wear on your flight. Consider your footwear carefully too, as swollen feet can be a side effect of flying. Flat shoes which are slightly roomy are always a good idea.
• Caused by sustained periods of inactivity, deep vein thrombosis (DVT) is a blood clotting condition that can affect some passengers on long-distance flights. The good news is there are proven ways to significantly reduce the risk of developing it. Stay hydrated, wander through the cabin as much as possible and wear compression tights or socks.

It's easy — be prepared. We've compiled some top tips for a fuss-free trip through airport security. Look out National City, here you come:

• Security personnel first need to determine that you have a valid passport and matching travel documents before anything else. Keep them within easy reach.
• The X-ray machine comes next. Remove anything on you that is likely to set off the scanner's alarm. This includes things like headphones or earphones, as well as bulky coats or jackets. They'll need to be placed on the conveyor belt for screening.
• Your electronic devices like laptops and phones will also need to go on a tray for inspection. Don't worry though, you'll be back online in no time.
• Remove all gels and liquids from your hand luggage. They often need to be sent through the X-ray separately. Each product should be no larger than 3.4 ounces (100 milliliters) and everything must fit inside a single quart-size (one liter), clear zip-close bag.
• Slip-on shoes are a practical footwear choice as you're less likely to be required to remove them when going through security. Boots and other heavy-style shoes are often subjected to extra screening.
• Take all prohibited items out of your carry-on bag. If you have any sharp objects like a pocket knife or tools, pack them safely away in your checked luggage. They won't be allowed on board.
